Frame Rails



One of the best performance upgrades for the Miata! Frame rails aid in additional rigidity to the MX5 Miata uni-body. Our rails are made from 14 gauge mild steel laser cut and CNC profiled to ensure the tightest fit and best performance. Finished in heavy-duty powder coating. 11 fastening points for each rail using 7/16th grade 8 zinc plated hardware. Can be used as jacking points. This product comes with two frame rails per unit ordered. Now with provisions for fuel line clips on passengers side rail.


New Gen2 rails – We’ve updated the outer edge for a scalloped edge to better conform to the uneven uni-body surface. Added reliefs for the stock fuel & brake line mounting points. Improved fitment to the trailing edge of the rails to suit the OEM structure.

Here are our official Frame Rail installation instructions. Here’s another great write-up on how to install these rails on your MX-5.

Frame rails

Excellent product. All the nuts and bolts were included.
Fast delivery.

It fits perfectly my Miata 1990.

Merci beaucoup.

Leslie Toczko
solid frame

Lots of hard work for two people setting frame, drilling holes and torquing bolts. Hopefully this will improve the overall performance.

Jacob Whitener
I like the stiffness

I enjoy how much rigidity it added to the chassis but did not like having to move the fuel lines so much. I wish there was a way to attach the factory brackets for the lines to the rails.
